Bad problem matic indicators

We bought a Nissan Magnite and don't have this vehicle for more than six months but I had to take it back for my front right hand indicator that just stop working.When I went to collect my vehicle I was told to pay almost a plus minus R1000 but the vehicle was still under warranty but clearly this lady wasn't doing her work right.Then by luck service manager walked in and he heard me saying this car is brand new look at the mileage and he took a look at the invoice and told me sir you don't have to pay and told her just bring the paperwork to me I'll sort it out .But know I sit again with the same problem my front right indicator don't work at all .I think this is the worst car Iwe bought.
